       fstrace - Introduction to the fstrace command suite


       The commands in the fstrace command suite are the interface that system
       administrators employ to trace Cache Manager operations for debugging
       purposes. Examples of Cache Manager operations are fetching file data
       or the status information used to produce output for the UNIX ls

       The fstrace command interpreter defines an extensive set of Cache
       Manager operations as the "cm" event set.  When the event set is
       activated, the Cache Manager writes a message to the "cmfx" trace log
       in kernel memory each time it performs one of the defined operations.
       The log expands only to a defined size (by default, 60 KB), after which
       it is overwritten in a circular fashion (new trace messages overwrite
       the oldest ones). If an operation of particular interest occurs, the
       administrator can afterward display the log on the standard output
       stream or write it to a file for later study. For more specific
       procedural instructions, see the IBM AFS Administration Guide.

       There are several categories of commands in the fstrace command suite:

       ·   Commands to administer or display information about the trace log:
           fstrace clear, fstrace lslog, fstrace setlog.

       ·   Commands to set or display the status of the event set: fstrace
           lsset and fstrace setset.

       ·   A command to display the contents of the trace log: fstrace dump.

       ·   Commands to obtain help: fstrace apropos and fstrace help.


       All fstrace commands accept the following optional flag.  It is listed
       in the command descriptions and described in detail here:

           Prints a command’s online help message on the standard output
           stream. Do not combine this flag with any of the command’s other
           options; when it is provided, the command interpreter ignores all
           other options, and only prints the help message.


       To issue most fstrace commands, the issuer must be logged on as the
       local superuser "root" on the machine that is generating the trace log.
